Preparedness for a major accident
Being prepared to respond quickly and effectively to a major aviation, rail or marine accident is a key function of the ATSB. To maintain preparedness, the ATSB actively participates in practical exercises to test the effectiveness of response arrangements. The ATSB also has a Major Investigation Preparedness Plan (MIPP). The MIPP includes a comprehensive suite of procedures and information. The MIPP and preparedness activities ensure that the ATSB is ready to respond effectively to a major transport accident.
